SASH-CURTAIN FRAME.

To all 'whom it may concern:

Be it known that I, DIGKRAN M. SAR- KlsmN, a citizen of the United States, and resident of Malden, county of Middlesex, State of Massachusetts, have invented an Improvement in Sash-Curtain Frames, of which the following description, in connection with the accompanying drawing, is a specication, like letters on the drawing representing like parts.

This invention has for its object the productionof a simple and strong frame for sash-curtains, so constructed and arranged that the making of the frame is made easier and it can be readily fitted into the opening of a window sash.

Sash-curtainsare now held in position in various ways, one very common arrangement consisting offrods attached to the top and bottom of the sash by small brackets, the curtain being mounted on the rods. This device requires considerable care in its application, for if the rods are not just the right length, or the brackets are spaced apart incorrectly they will not cooperate with the rods, and the brackets must be fastened in place by means of small screws.

In my present invention I provide four corner-pieces, channeled to receive the top, bottom and side bars of the frame, and so arranged that if a bar is not out just the right length it may still be used, each cornerpiece having means to prevent the ends of bars at right angles to each other from interfering.

In my preferred form of construction the bars are flat, and the frame rests within the opening of the sash, against or adjacent the glass, and is held in place by suitable means, as screw-eyes, which can be given a part turn when it is desired to remove the sashcurtain.

Figure l is an inner front elevation of a window sash with a curtain frame applied thereto embodying my invention, the sides, top and bottom of both the sash-curtain frame and the sash being broken out to save space; Fig. 2 is an enlarged view of one of the corner-pieces of the curtain frame, showing the means for preventing interference of the ends of adjacent bars; Fig. 3 is a crosssection thereof on the line 3 3, Fig. 2. Fig. 4 is a perspective detail of the corner of one of the corner pieces.

In Fig. 1 a window sash of any usual construction is shown, comprising the lower Specification of Letters Patent.

rail l, upper or meeting rail Q, and the side rails 3, tixedly connected in any suitable manner and in practice carrying a pane of glass in the opening.

In accordance with my invention the sashcurtain comprises four corner-pieces and connecting bars detachably mounted on them, the sash-curtain being supported on the top and bottom bars of the frame.

One of the corner-pieces is shown enlarged in Fig. 2, and in practice is made of sheet metal, of substantially L-shape in plan, the longitudinal edges of the arms Il, l being flanged at 5 and inturned at 6, Fig. 3, to form two intersecting channels on the face of the corner-piece.

A diagonal shoulder or stop 7 is made in the angle of the corner-piece, (see Figs. l, 2, and 4l) the shoulder crossing the bottoms of the two channels at their intersection, for a purpose to be described.

Flat and preferably metallic bars S and 9 are connected with the corner-pieces by sliding an end of each bar into one of the channeled arms, the bars S being at the top and bottom of the frame and the bars 9 at the sides thereof, as in Fig. l. The bars are cut to substantially the proper length, but as they are slidable in the channeled arms and held therein frictionally it is not necessary to cut the bars exactly accurate, as the length ofthe arms l of the corner-pieces permits some leeway in fitting, as will be manifest. As the backs of the corner-pieces are flat they will rest squarely upon the pane of glass, in the corners of the sash, and the frame can be held in place by screw-eyes l0 in the side rails of the window sash, Fig. l, which can be turned into dotted line position when it is desired to remove the frame.

The sash-curtain C is shown in part only in Fig. l, and is mounted on the top and bottom bars by means of hems, through which the bars are run.

By the device shown the curtain is brought close to the glass, it can be easily applied or removed, and to put up one of the frames no skilled labor is required.

To prevent the ends of the adjacent bars 8 and 9 connected by a corner-piece from interfering I provide each corner-piece with the diagonal shoulder or stop 7 which is raised slightly above the bottoni of the intersecting portions of the channels, this shoulder' preventing the end of a bar from passing into the angle of the corner-piece.

Thus neither of the two bars can interfere with the other, and any distortion of the frame is prevented.

Having fully described my invention, what I claim as new and desire to secure by Letters Patentis zl. A sash-curtain frame comprising L- shaped corner-pieces having their longitudinal edges flanged and inturned to form channels on the face of the corner-pieces, a diagonal stop crossing' the angle of each corner-piece and tlat connecting bars slidable into the channels, the stop in each corner piece preventing the projection of the end of either bar into the path of the other bar.

Y 2. As a new article of manufacture, an L- shaped corner-piece for sash-curtain frames, made of sheet metal and having its longitudinal edges l'langed and overturned, to form intersecting channels on the face of the corner-piece, and having also a diagonal shoulder crossing the bottoms of the channels at their intersection and forming a stop.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses.
